Yes, here is an example: A post-production house in New-Zealand transfer files to and from its LA office. Their 50Mbps link costs $1,000/month and is theoretically very fast. However, the average latency of a Pan-Pacific transfer is 200ms with an average packet loss of 1%. Under these conditions, FTP will only transfer at 490Kbps or 1% of the pipe capacity.
With the UDP-based acceleration, transfer speed will reach near link speed or 100x faster than FTP. What formerly took hundreds of minutes now takes only one. Without spending more money the company has regained 99 precious minutes which can be used for more productive tasks.
